To the Reader

There are two main purposes for adding this extra chapter.

1. (a) To provide abbreviated solutions for all exercises appearing at the end of each chapter.

2. (b) To provide some suggestions to instructors and to the general reader regarding which topics to emphasize, and to comment on the general logic behind the specific ordering of the topics covered in each chapter.

I emphasize abbreviated solutions because I see no need to repeat all the steps developed in the body of each chapter. All I want is to provide the reader with some feedback on whether they can independently solve the kind of problems analyzed in this book. However, students should be required to submit their homework in greater detail than that given in this manual, using all the steps developed in the body of each chapter.

Some instructors may not like the fact that the solutions for all exercises are provided as this will require them to write more exercises for homework and exam purposes. However, I can assure the instructors that even if they do not assign any formal homework, students will learn much better if they can train themselves by looking at the solutions to the problems they are supposed to know how to solve.
